When you use a slingshot to fire a rock you stretch the rubber band storing potential energy. You stretched the rubber band so that it had 100-J of potential energy. When you calculated the kinetic energy, you calculated the rock to only have 90-J of energy. What happened to the other 10-J?

A. It was lost in flight

B. It was transformed to sound and thermal energy

C. The calculations are wrong

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
